Plastic Machinery

Liquid crystal televisions and monitors, mobile phones and smartphones use plastic components with advanced optical properties. Integrated plastic extrusion systems from Hitachi Zosen are used to make film and sheet products with excellent characteristics including flatness, transparency and thickness accuracy as well as low residual strain.
Hitachi Zosen also supplies sheet manufacturing equipment used to make photovoltaic cell panels along with a wide range of extruders for food packaging, construction materials, electrical appliances and auto parts.

Film-forming machine with elastic metal roll (UF roll)

Hitachi Zosen's film-forming machine with elastic metal roll (UF roll) is the heart of our optical film and sheet molding system and functional film-forming system. Even though the outer cylinder is a metal roll, it is so thin that its elastic deformation is high like rubber, and therefore, even for thin films, roll pressure formed by low line pressure can be used to obtain film products that are superior in gloss and transparency.

General-Purpose Film and Sheet Forming Systems

We offer a variety of systems to respond to all our customers' needs such as film and thin sheet-forming systems, multi-layer thin sheet-forming systems, and foamed sheet-forming systems.
